Instance member guarded by static field
Reports @GuardedBy annotations on instance fields or methods in which the guard is a static field. Guarding a non-static by a static may result in excessive lock contention, as access to each locked field in any object instance will prevent simultaneous access to that field in every object instance.
Example:
private static ReadWriteLock lock = new ReentrantReadWriteLock(); //static guarding field
private Object state;
@GuardedBy("lock")
public void bar() {
state = new Object();
}- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

You can suppress this inspection by placing the following comment marker before the code fragment where you no longer want messages from this inspection to appear:
//noinspection InstanceGuardedByStaticnote
Actual comment syntax will depend on the code language you are working with
